For those waiting on the latest lineup of MacBook Pro models to arrive -- the Apple Insider is expecting that the date might be pushed to sometime in November, possibly due to some problems that have sprung up in the Taiwan factory that manufactures the uni-body MacBook cases.
Apple Insider cites these expected improvements:
The speed bumps to this year's models will be made possible through a quite [sic] refresh to Intel's Sandy Bridge lineup of processors introduced in early September. The company added four new Core i7 branded chips that would be likely candidates to advance the MacBook Pro's performance. For instance, the latest 2.4GHz, 2.5GHz and 2.7GHz quad-core CPUs could respectively replace the 2.0GHz, 2.2GHz, and 2.3GHz currently found in Apple's 15- and 17-inch MacBook Pros.
Meanwhile, those who are looking for better performance might benefit from adding more RAM to the latest 64-bit models, as suggested by CNET's Topher Kessler. Kessler says that, in theory at least, the 64-bit models should be able to handle up to 16GB RAM -- double the stated 8GB limitation.
Even though they are 64-bit capable, Apple's MacBook Pro systems have been offered with 8GB RAM as the maximum configuration. More recent models, including those released in 2011, have been built with a higher RAM limit, so even though Apple only offers 8GB RAM and mentions this as the maximum amount of RAM the systems can hold, in reality they can recognize up to 16GB if you add it.
